In addition, several sequels have been launched. The original game was released in 2008 for PC and was adapted for smartphones by 2015. By 2019, Playrix changed the gaming concept to ' freemium', in which various currencies such as diamonds can also be purchased in the app.

The platform also provides mini-games, holiday-themed upgrades, pearl tournament challenges, and 3D-simulation of a scuba mask which allows the user to dive into the deep sea. The puzzle board should be cleared before the player runs out of moves otherwise the player has to do the level again in order to progress to the next level. When three or more objects are matched simultaneously, one of the bonuses appears: firecrackers, depth bombs, dynamite charges, or lightning. Some of the tiles are locked and have a different color to unlock them the player should match gems over a couple of times.

Each of the rounds takes place on a different grid and poses a challenge earning every golden tile by matching gems over them at least once. Levels are based on a standard for ' match three' mechanics: the player swaps two adjacent gems to make matches of three or more. Adorned and themed tanks can be used as a smartphone screensaver. Filling all of the three meter gauges measuring the progress will unlock one of the trophies: bronze, silver, or gold. Using in-game currency the player is able to purchase different species of fish, decorations, and 'comfort' items to make the environment more pleasant for pet fishes. The object of the game is to solve puzzles and earn coins to set up and decorate a virtual aquarium.
